Seal Technology the P3 Diaphragm

SÜDMO SEAL TECHNOLOGY THE P3 DIAPHRAGM

FOOD & BEVERAGE P3 DIAPHRAGM SÜDMO’S ADVANCED ASEPTIC SEAL TECHNOLOGY THE P3 DIAPHRAGM Südmo sets the industry standard with its P³ diaphragm seal material for use in a wide range of aseptic valves. The P3 diaphragm’s shape along with the material properties provide outstanding performance in terms of chemical and temperature resistance, as well as pressure and load cycle resilience compared to other options on the market, including metal bellows. The P3 diaphragm provides many advantages in various process areas and aseptic applications.

• Extremely good chemical resistance

• Temperature resistance up to 150 °C (302 °F)

• Dynamic working pressure up to 10 bar (145 psi)

• High number of cycles > 300,000

Already standard in the pharmaceutical Due to product liability processors must Challenges incude automated Cleaning industry, the use of aseptic production and protect consumers from the risk of health- in Place/Sterilization in Place (CIP/SIP), packaging is growing rapidly in the beverage, damaging germs and bacteria. This minimized cleaning times and cost-effective, food and dairy industries. Consumer trends increases the procedural and economic simple and fast maintenance. toward natural chemical-free products, optimization requirements that are imposed extended shelf life (ESL) options, and by the manufacturers on the suppliers of the unique packaging that requires cold filling respective components. challenges production plants to process microbiological sensitive products.

UTILIZATION OF THE P3 DIAPHRAGM

The P³ diaphragm is applied in the Südmo SVP Select Single Seat Valve series and the Aseptic Mix Proof Secure Valves. In both valve types the advanced seal technology supports all performance areas of the proven Südmo valve technology, including Südmo’s minimized maintenance requirements and easy service handling.

The term aseptic, when applied to valve design, generally means to eliminate atmospheric contact with the product as made possible with a standard hygienic valve. Depending on system design and valve type, processors have become accustomed to performing maintenance at intervals as frequently as once a week to a maximum of about three months. This is in large part due to three variables - temperature, chemicals and pressure shocks. Metal bellows have traditionally been a standard option for aseptic valves. Made from either stainless steel with elastomer seat, or entirety Teflon®, bellows have many limitations.

High spare parts costs. When replacement is necessary high-quality Cost-effective, because only the diaphragm is replaced. Due to the stainless steel parts, such as the valve seat or the upper socket, are AREA P³ DIAPHRAGM ADVANTAGE design, Südmo valves are quick and easy to repair and maintain. disposed. Improved equipment efficiencies, better protection of downstream equipment, Double-walled bellows will not provide secure leakage and minimized batch contamination due to the more reliable diaphragm. Shorter Operation and Environment Unimpeded secure and easy leakage detection. management. There is a risk of contamination between the layers and easier cleaning cycles reduce the overall demand for media (water, caustic / of the metal bellows. acid concentrates).

A longer diaphragm service life increases process run time and reduces labor Maintenance Costs and documentation costs for membrane replacement.

Only the P3 diaphragm is replaced, which reduces spare parts and inventory Spare Parts carrying costs.

Based on the service life over several years you will see significant cost Cost Savings savings, improved product conditions, and longer process run times.
